The proposal is a welcome move to re-align defintions that should not have been unaligned. It's been suggested that the revised definition of "Vocal score" more closely parallel the language in the current RDA definition for "Chorus score." It would thus read "A score showing all vocal parts, with the instrumental accompaniment either arranged for one or two keyboard instruments or omitted."
